Description

Technical Field

[0001] This utility model relates to the field of railway vehicle maintenance, specifically to a device for measuring the gap between the skirt and bottom plate of a high-speed train. Background Technology

[0002] In the maintenance of high-speed trains, measuring the installation dimensions of the skirt panels is a crucial step in ensuring safe operation. Currently, on-site personnel typically use steel rulers for measurement, but this method suffers from numerous inconveniences and inefficiencies. For example, measuring skirt panel height differences with a steel ruler is difficult, measuring skirt panel gaps and end plate gaps is inefficient, and during cabin sealing operations, up to 700 dimensions need to be measured, involving a wide variety of measurements in complex environments. Using a steel ruler for such a large volume of data measurement is not only inefficient but also puts personnel in a highly concentrated state for extended periods, easily leading to fatigue and reading errors. Therefore, a new tooling is needed to improve measurement efficiency and accuracy. Utility Model Content

[0003] In view of the above-mentioned defects or improvement needs of the existing technology, this utility model provides a high-speed train skirt bottom plate gap measuring device, which includes a skirt bottom plate gap measuring arm, a skirt bottom plate height measuring arm, an end plate measuring arm, and a depth measuring arm connected in sequence from front to back.

[0004] The base plate gap measuring arm is a block structure that is narrow at the front and wide at the back. Width scale lines are set on both sides of its upper surface. Its front end is inserted into the gap to measure the gap width.

[0005] The front end of the skirt bottom plate height measuring arm is fixedly connected to the rear end of the gap measuring arm. The skirt bottom plate height measuring arm has a center length scale line in the middle part of the upper surface of the skirt bottom plate height measuring arm and the gap measuring arm, so that the height measuring arm and the gap measuring arm can be used together to increase the longitudinal measurement distance. The skirt bottom plate height measuring arm has scale lines on one or both sides.

[0006] The end plate measuring arm is a block structure. One end of it is fixedly connected to a narrower depth measuring arm, and the other end is detachably connected to the rear end of the skirt bottom plate height measuring arm. The end plate measuring arm and the bottom plate height measuring arm have protruding parts, and their side surfaces are provided with scales for measuring the end plate thickness.

[0007] The depth measuring arm is a long rectangle with graduations on its side for depth measurement.

[0008] Furthermore, the scale lines on both sides or one side of the skirt bottom plate height measuring arm correspond to the middle scale line by setting the same minimum scale, which facilitates reading the degree of the middle scale.

[0009] Furthermore, the scale lines on both sides of the skirt bottom plate height measuring arm are set as two zero points, one at the front end and one at the rear end, with different directions, to facilitate measurement from both ends of the skirt bottom plate height measuring arm.

[0010] Furthermore, multiple reflective color blocks are set in the scale area corresponding to the side of the skirt bottom plate height measuring arm. Different color block areas represent different standards, allowing for quick determination of whether the size meets the standard during measurement.

[0011] Furthermore, the end plate measuring arm and the skirt bottom plate height measuring arm are connected by a detachable connecting device, which includes magnets installed on the end plate measuring arm and the skirt bottom plate height measuring arm respectively, or grooves and protrusions that can be interlocked on the end plate measuring arm and the skirt bottom plate height measuring arm respectively.

[0012] Furthermore, a miniature LED light is installed at the end of the depth measuring arm, which can be turned on to illuminate the measurement area inside the skirt panel when performing depth measurement.

[0013] Furthermore, the gap measuring device is made of aluminum alloy or stainless steel.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Please refer to Figure 1 A high-speed train skirt bottom plate gap measuring device includes a skirt bottom plate gap measuring arm 2, a skirt bottom plate height measuring arm 3, an end plate measuring arm 4, and a depth measuring arm 5 connected sequentially from front to back. The device can be made of aluminum alloy or stainless steel, which has the advantage of relatively low density, making the overall measuring device lighter, easier for staff to carry and operate, less prone to rust and corrosion, and extending the service life of the device.

[0026] Please refer to Figure 2 The base plate gap measuring arm 2 is a block structure that is narrow at the front and wide at the back. Width scale lines are set on both sides of its upper surface. When its front end is inserted into the gap, the gap width can be measured. The scale is set according to the correspondence between the gap width and the scale lines of the base plate gap measuring arm 2.

[0027] The skirt height measuring arm 3 and the gap measuring arm 2 are different parts of one body. A center scale line 31 is provided in the middle part of the upper surface of the skirt height measuring arm 3 and the gap measuring arm 2, so that the height measuring arm 3 and the gap measuring arm 2 can be used together to increase the longitudinal measurement distance; scale lines 32 are provided on both sides of the skirt height measuring arm 3.

[0028] The scale lines 32 set on both sides or one side of the skirt bottom plate height measuring arm 3 correspond to the middle scale line by setting the same minimum scale, and the dotted lines connect the scales on both sides and the middle scale, so as to facilitate reading the degree of the middle scale. At the same time, the scale lines on both sides or one side can be used independently.

[0029] The scale lines 32 on both sides of the skirt height measuring arm 3 can be set as two scale lines with opposite zero points, one at the front and one at the rear. One scale line is used to read the height scale using the center scale line 31 when the skirt height measuring arm 3 is used in conjunction with the gap measuring arm 2. The other scale line is used to hang the object to be measured with the protruding part of the end plate measuring arm 4 relative to the skirt height measuring arm 3 as the starting point, and to directly read the length.

[0030] Please refer to Figure 3 Multiple reflective color blocks 33 can be added to the corresponding scale area on the skirt bottom plate height measuring arm 3 to quickly determine whether the size meets the standard during measurement. If the measured bottom plate height is within the qualified range, it can be quickly identified.

[0031] Please refer to Figure 4 The endplate measuring arm 4 is a rectangular structure integrated with the depth measuring arm 5. Its other end is detachably connected to the skirt panel height measuring arm 3 via a connecting device. This detachable connection can be achieved by installing magnets on the endplate measuring arm 4 and the skirt panel height measuring arm 3, or by using grooves and protrusions on the endplate measuring arm 4 and the skirt panel height measuring arm 3 for fastening. The side surface of the endplate measuring arm 4 has graduations for measuring the endplate thickness. The endplate measuring arm 4 and the skirt panel height measuring arm 3 have protruding parts, meaning their widths and heights are different. The depth measuring arm 5 is a long rectangular strip with graduations on its side for depth measurement. A miniature LED light can be installed at the end of the depth measuring arm 5, and a button can be installed on the endplate measuring arm 4. When performing depth measurements, the lighting function can be activated to illuminate the measurement area inside the skirt panel.

[0032] How to use:

[0033] Method 1: Gap measurement. Insert the skirt bottom plate gap measuring arm 2 into the gap to be measured and read the width on both sides of the scale line of the skirt bottom plate gap measuring arm 2.

[0034] Method 2, height measurement: Place the bottom plate gap measuring arm 2 and the bottom vertical measuring head 1 close to the bottom surface, and directly read the installation height of the skirt bottom plate through the skirt bottom plate height measuring arm 3 and the center scale line 31. Then, compare the measured item with the color block 33 on the side of the skirt bottom plate height measuring arm 3 to quickly determine whether the size meets the standard.

[0035] Method 3: Direct measurement. Hook the object to be measured at the protruding part of the end plate measuring arm 4 relative to the height measuring arm 3 of the skirt bottom plate, and read the length directly through the scale line on one side of the height measuring arm 3.

[0036] Method 4, thickness measurement: Taking the protruding part of the skirt bottom plate height measuring arm 3 relative to the end plate measuring arm 4 as the starting point, align the object to be measured with the protruding part of the skirt bottom plate height measuring arm 3, and read the scale on the end plate measuring arm 4.

[0037] Method 5: Measure the depth. Turn on the light to check for foreign objects at the measurement site. Insert the depth measuring arm 5 into the measurement site and read the scale on the depth measuring arm 5.

[0038] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
